The equation for the dark reaction of photosynthesis in C-3 plants is as follows:

A.	ribulose-1,5-bisphosphate carboxylase, or RUBISCO is the CO2-fixing enzyme for this process.
B.	the reactions occur in the chloroplast stroma.
C.	the ATP and NADPH required for this process are produced by the light reactions of photosynthesis.
D.	this process is the primary source of reduced, carbon-containing compounds for all living organisms.
E.	all of the statements are true.

RUBISCO is the CO2-fixing enzyme for this process. See the tutorial for problem #1 of problem set 2 of Photosynthesis.

The reactions occur in the chloroplast stroma. See the tutorial for problem #1 of problem set 1 of photosynthesis. and the tutorial for problem #2 of problem set 2 of photosynthesis.

The ATP and NADPH required for this process are produced by the light reactions of photosynthesis. See the tutorial for problem #8 of problem set 1 of photosynthesis

Carbohydrate biosynthesis occurs via enzymes of the Calvin Cycle. See the tutorial for problem #2of problem set 2 of photosynthesis.

This process is the primary source of reduced, carbon-containing compounds for all living organisms.
